What is a short code? Do I need one?
A shortcode (officially called a Common Short Code) is a short number (generally 4-6 digits long) to which a text message (SMS) can be sent from a mobile phone. Shortcodes are useful because they save you from having to memorize an entire 10-digit number. For example, to send a text message to 4INFO you just send a text message to 44636 (it spells 4INFO on your keypad). It’s like a phone number for text messaging only, and you don’t need one to advertise on the 4INFO network.
